when i was having my "issues" Scott Bell of SACC Restorations was kind enough to provide a list of the items needed to convert to the T. Here is the list:
Brass Union - 5/16" Line - Both Sides Female SAE 1/2" X 20 Thread - Inverted Flare - Pack of 10

Earl's 972055ERL Brake Adapter

Brake Light Switch with 3/8 Inch IFM Adapter Fitting
https://www.amazon.com/gp/prod...;smid=A1FJ1WMPKJVUMQ
This is all you need along with a slight amount of bending the existing brake lines and maybe one or two new flares
